Problems solved by technology

At present, the artificial culture of Splendid lobster is still in the initial stage of exploration. The main breeding method is conventional floating cage culture. This breeding mode has disadvantages such as high cost, low breeding survival rate, and poor environmental controllability, which is not conducive to the promotion of industrialization. , seriously restricting the development of the splendid lobster aquaculture industry, so it is necessary to find a new method suitable for the industrialized cultivation of the splendid lobster

Embodiment 1

[0041]In this example, the effect of three different baits feeding Splendid lobster on its growth and survival rate was studied. Splendid lobster seedlings (body weight 0.82±0.12g) were selected for the experiment, and three treatment groups were set up, and excessive amounts of Philippine clam, mackerel and oyster meat were fed respectively, and 10 replicates were set for each treatment. During the experiment, the young lobsters were fed twice a day at 8:00 and 18:00, and the lobsters were weighed after one month of breeding to calculate the specific weight gain rate and survival rate. The results are shown in Table 1, indicating that the type of food has a significant impact on the growth and survival rate of Splendid lobster, and the maximum specific growth rate and survival rate were obtained in the oyster meat group, which were significantly higher than those in the Philippine clam group and mackerel meat group ( P<0.05), oyster meat is more conducive to the growth of lob...

Embodiment 2

[0046] In this embodiment, there are 10 cement culture ponds of 4m x 4m in the breeding workshop. The body length of the selected lobster seedlings is 2cm, and 1500 lobster seedlings are put in. The specific implementation process is as follows:

[0047] 1. Use cement breeding ponds, use natural seawater with a salinity of 28-33‰, the seawater depth in the cultivation ponds is 90cm, and install inflatable pipes around the bottom of the cultivation ponds to keep the dissolved oxygen in the water above 5mg / L.

[0048] 2. Seven days before preparing to release Splendid lobster seedlings, soak the entire breeding pond, floating nets and shelters with 30ppm oxalic acid and clean them with clean water, then add sand-filtered seawater to the breeding pond.

[0049] 3. Temporarily raise Splendid lobster seedlings in floating net cages, and the breeding density of shrimp seedlings is 200 tails / m 2 , using 16 net cages in total, put them in 2 cement pools, the specifications of the net ...

Embodiment 3

[0058] In this embodiment, there are 10 cement culture ponds of 5m x 5m in the breeding workshop. The body length of the selected lobster seedlings is 2cm, and 1500 lobster seedlings are put in. The specific implementation process is as follows:

[0059] 1. In each aquaculture pond, use bricks and cement boards to build a cultured lobster enclosure with a size of 20cm×20cm, build 2 layers, and a height of 50cm. The single-layer aquaculture enclosure covers 30% of the area of ​​the cement pool; at the same time , laying a layer of oyster shells on the bottom of the culture pond and the outside of the culture fence, the oyster shells account for 20% of the culture pond area;

[0060] 2. Use 30ppm oxalic acid to sterilize the culture pond and the multi-layer culture cage built. When disinfecting, water needs to be kept in the breeding pond, and the water is submerged in the breeding enclosure so that the sprinkled oxalic acid can be evenly distributed, and the sand-filtered seawa...

Abstract

The present invention provides a method for industrialized culture of Splendid Lobster, which belongs to the technical field of Splendid Lobster cultivation. The present invention not only provides a hidden habitat for Splendid Lobster, but also realizes the cultivation of young shrimp High-density breeding ensures the number of beautiful lobsters per unit area, which is more conducive to the habitat of lobsters; in addition, the most suitable fresh oysters are fed during the breeding process, so that the lobsters have the best survival rate and the fastest growth rate. The present invention adopts the indoor three-dimensional flowing water breeding method, scientific and reasonable stocking density and feeding amount, and is a brand-new breeding mode under artificially created optimal conditions. Compared with traditional breeding methods, it has higher breeding output per unit area. High, short breeding cycle, low breeding cost, high production efficiency and controllable environment, etc., has a wide range of application prospects.

Description

technical field [0001] The invention relates to the technical field of lobster cultivation, in particular to a method for industrialized cultivation of lobsters. Background technique [0002] Splendid lobster (Panulirus ornatus) belongs to Crustacea, Decapod order, Lobster family, Lobster genus. Coastal fishermen in my country also call this kind of lobster "green dragon", "flower lobster" or "colorful lobster". Splendid lobster is the largest of the lobster genus, its body length can reach 60cm, and its weight can reach more than 3kg. In my country, it mainly inhabits the coral reefs and rocks around the islands and reefs in the South China Sea. It is deeply loved by consumers because of its delicious taste. , and has been regarded as a treasure in the sea since ancient times, so its price is also very high. Splendid lobster is a rare economical shrimp in the world. With the increasing demand for lobster in the market, wild Splendid lobster resources have decreased sharply...
